FLUE-BRUSH.

SPECIFICATION forming part of Letters Patent No. 477,074, dated June 14, 1892. Application filed March 17, 1392. Serial No. 4 5,8 1- (N model To all whom it may concern.-

Be it known that I, LLEWELLYN B. SHULTZ, of St. Louis, Missouri, have made a new and useful Improvement in Flue-Brushes, of which the following is a full, clear, and exact description.

The improvement relates to that class of flue-brushes in which the tufts of the brush are held in a set of staves, which unitedly constitute a cylindrical head therefor. In such brushes this difficulty is experienced: Owing to said head being made in sections, as described, the tufts cannot be inserted continuously around the head. The staves are perforated to receive the tufts, and as the perforations cannot occur at the joints between the staves and have to be spaced a certain distance in from the edges of the staves gaps occur in the finished brush along the lines of the joints referred to. To obviate the difficulty referred to and to provide an improved fiuebrush are the aims of the present improvement, which consists, partly, in so constructing and combining the staves as to cause in a portion of the brush a row of tufts to come opposite the joint in another portion of the brush, partly in arranging the lines of tufts in one half of thebrush opposite the spaces between the lines of tufts in the other half of the brush, and partly in dividing the staves transversely to enable the portions of a stave to be relatively adjusted for the purpose described or other purposes, all substantially as is hereinafter set forth and claimed, aided by the annexed drawings, making part of this specification, in which Figure 1 is a side elevation of one of the staves; Fig. 2, an end elevation thereof, including, in broken lines, the remaining staves of the brush-head; Fig. 3, a side elevation of the improved brush, not including the tufts; Fig. 4, an end elevation of the brush; and Fig. 5, a viewin side elevation showing the central portion of the brush-head, the staves being divided transversely and the lines of perforations in one end of the brush-head being respectively opposite the spaces between the lines of perforations in the opposite end of the brush-head.

The same letters of reference denote the same parts.

The brush A is of the usual construction, saving as modified orsupplemented by the improvement under consideration. B B B represent the staves composing the brush head. Any desirable number of staves may be used, and they are united by means of the end pieces C O and the bolt D and nut E 1n the usual manner. The staves, in place of being made with straight side edges, have at each side edge an offset 1) and a pro ect-ion b. The offset extends, say, one half the length of the stave and the projectlon the other half thereof, and when the staves are assembled to form the brush-head the projection upon one stave enters the offset in the abutting stave, substantially as is represented in Fig. 3, and the perforations b in a projection I) come opposite the joint w between the opposite ends of the abutting staves. Therefore in the finished brush no gap in the tufts can occur continuously throughoutthe length of the brush.

The improvement is carried out more effectively when the lines of perforations in one half-say the half CL-Of the brush come, respectively, opposite the spaces between the lines of perforations in the opposite half a of the brush, substantially as is represented in Fig. 5. By this means the tufts F in one end of the brush are caused to be arranged opposite the spaces which occur between the tufts F in the opposite end of the brush, and the brush when viewed endwise presents the appearance exhibited in Fig. 4.

To strengthen the staves, they are prefer ably at the line of the offsets referred to pro" vided with a collar or'flange b substantially as is represented in Figs. 1 and 3. Said collar or flange is, as well as the offset described, shaped substantially as shown to provide a space G to facilitate the assemblage of the staves, which otherwise, from imperfect fitting of the parts, might be hindered. Fig. 5 illustrates an additionalfeature. The staves are divided transverselyinto two parts I) and U, which are united by means of the bolts b passing through the flanges upon the staves or otherwise, substantially as shown. It is obvious that by this means the two parts of the stave can be relatively arranged to cause the lines of perforations in one part of the stave to be out of line With those in the other part of the stave.

I claim 1. A flue-brush having its staves divided 5 transversely and united substantially as and for the purpose described.

2. A flue-brush Whose staves have oitsets and projections at their side edges and having in one part of the brush-head a row of projec-.

IO tions opposite the joint between the staves in the opposite part of the brush-head and said staves being divided transverselyand united substantially as and forthe purpose described.

WVitness my hand this 12th day of March, 1892.
